Hello Guys,
I am getting 1 error, with Sender channel, Which keeps in retrying mode after other systems queue manager ended and started for the backup purpose(Machine 1) , I have checked the listener for the another queue manger(Machine 1), its runing fine but the sender channel on Machine 2 keeps in retrying untill you start the channel.
=============================================
AMQ9209: Connection to host '10.54.19.212' closed.
EXPLANATION:
An error occurred receiving data from '10.54.19.212' over TCP/IP. The
connection to the remote host has unexpectedly terminated.
ACTION:
Tell the systems administrator.
============================================

Thanks.
Lothar. |

Two things I'd try.
First, explicitly stop the channel in runmqsc.
Then try:
PING CHANNEL(channel name)
and look at the result. This might give you some additional insight into the problem.
Next, start the channel using runmqchl from the command line. This way usually provides a much more verbose explanation of why it cannot start the channel properly.
Unfortunately, there are so many reasons why you might be getting that (very generic) error message that it is unlikely anyone can help you diagnose it without additional information (like the results of the two tests above).

Make sure to check the reciever channel is defined on the remote machine. You can also use telnet to see if the reiever is running on a port. Just tellnet to the machine specifyling the port number. If MQ is listening thenyou will get some dialog... If it isn't running on the port then your connection should fail.. This is really just a sanity check.
Of course this requires to know what port number that MQ is running on. The port doesn't seem to be echoed in the error message you got. Make sure the sender has the correct port number.
Hope this is of some help. |

Hi ,
Thanks for the reply, Well everything seems to be fine, like when i ping its pinging correctly, even i started at the command promot using nohup runmqchl -c (CHLNAME> -m <QMGR) &.
The port number is 1416 and i am have checked everything non of the port is runing with this port number. still the problem is same.
I know when i stop the sender channel and start it this works fine. even i have checked the remote machine the receiver channel is runing but sender is in retrying mode. i dont understand what the problem.
Give me some hints ... |

When you stop sender channel, does receiver stop on the other side ?
If it's not then you need to configure adopt option on the receiver channel.

Hi,
When i stop the SDR channel then the RCVR Chl was running on the remote host. The moment i stops the Sender and start it again the SDR chl works fine and all the messages stucked in TransQ will passed to Remote Receiver Side.
What is configure adopt option ?? Can you explain me how ?? |

If your platform is Windows then use the Channels queue manager properties page,
otherwise use the Channels stanza in the qm.ini file.
AdoptNewMCA=RCVR
AdoptNewMCACheck=QM,NAME
For more information and adopting options look at System Administration Guide - Part 4 - Changing queue manager configuration information.

Hi Leonid,
Thanks!!! the senario our here is like We have a backup everyday and when backup hits its stops all the WMQ processes, and once the backup finished it again restart the MQ Process and once the MQ process started successfully along with the listener for the Remote QM, but when we checked the Remote QM SDR Channel its keep in Retrying mode though there are messages lying in the TransQ, and when you stop the SDR Channel, pinging is working fine even when you start the SDR channel it will work fine. I dont understand why its not triggering the SDR channel when the listner channel is runing at the other end.The OS is Unix.
As you have been adviced for the 2 parameters, could you please let me know on which QM which need to set at Sender Channels QM or Receiver Channels QM.
Kindly give me some hint or let me know if anyone has face this problem before. |

You need to configure it on the receiver side.
Sometimes, channel receiver doesn't recognize that a channel sender is stopped and just hanging up in the air.
Adopt option enables channel sender adoption. If receiver sees that some sender tries to connect
with the right name and from the right queue manager, then it drops previous connection and adopts the new one.
I suggest that you'll check also how your backup stops MQ tasks.
It seems that something wrong happens in this procedure.
( Always stop channel sender and receiver will stop automatically ).

Hi Leonid,
Thanks for the reply, I guess the backup procedure is correct becos it stops the MQgr and receiver Channels and once the backup finished it will start MQ Process along with receiver channel but the SDR will not be stoped at the other host it will be in retying mode untill he gets the Receiver channel up it will atmotically trigger it and the SDR will start.
Did you faced this problem before. |

Again, I'm not sure that the problem you have is adoption one.
Yes I have faced problems like this and this option has solved them,
but there are many cases when it can be something else.
Do you have error logs maybe with some additional info ?
